Hypergravity reduces astrocyte migration by altering cytoskeletal dynamics [PDF]

open access: yes, 2020
Glial scar formation through astrocytes impairs neural regeneration following spinal cord injury, head trauma, or stroke. Astrocyte migration towards the lesion and induction of a reactive astroglial phenotype require dynamic cytoskeletal protein ...

Tracking Spatiotemporal Mineral Dissolution Through Quantitative Nuclear Magnetic Resonance Signatures

open access: yesGeophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Mineral dissolution reorganizes pore space through spatiotemporally variable pathways, but non‐invasive tracking remains difficult. We test whether nuclear magnetic resonance (NMR) signatures can diagnose carbonate dissolution by integrating pore‐scale reactive transport simulations with forward modeling of T2 ${T}_{2}$ distributions for face ...

Enhancing hydrogen evolution reaction by harnessing bubble dynamics regulation: Principles, methods, and outlook

open access: yesDroplet, Volume 5, Issue 3, July 2026.
Bubble dynamics pose critical bottlenecks to hydrogen evolution reaction efficiency, causing active site isolation, increased ohmic resistance, and concentration overpotential, especially at high current densities. This review comprehensively summarizes passive and active bubble manipulation strategies, elucidates their underlying principles, and ...

Hypergravity and Aging in Drosophila-melanogaster .4. Climbing Activity [PDF]

open access: yes, 1992
Drosophila melanogaster flies climb up the sides of their vial after having been submitted to a mechanical stimulation; that ability is impaired at older ages.

Extreme-temperature oxidation behavior of nickel-based superalloys up to 1345 °C and the magnetic properties of their oxide layers

open access: yesMaterials & Design
The high-temperature oxidation behavior of DD6 and DD9 alloys at 1050, 1200, and 1345 °C for 5 h, together with the magnetic properties of the resulting oxide layers, was thoroughly investigated.

Light‑Driven Propulsion of Graphene Aerogels in Microgravity

open access: yesAdvanced Science, Volume 13, Issue 33, 15 June 2026.
Ultralight graphene aerogels convert laser light into thrust. Parabolic‐flight experiments directly compare their motion in microgravity and at 1 g, revealing order‐of‐magnitude enhancements in distance, velocity, and transient thrust when weight and friction are removed (∼50 times enhancement).

Gravity, a regulation factor in the differentiation of rat bone marrow mesenchymal stem cells

open access: yesJournal of Biomedical Science, 2009
Background Stem cell therapy has emerged as a potential therapeutic option for tissue engineering and regenerative medicine, but many issues remain to be resolved, such as the amount of seed cells, committed differentiation and the efficiency.
